IKEA loft bed and mattress

I have an IKEA loft bed with a desk and mattress.... Been used for a couple of years, a few marks as you can see in photos. Still in very sturdy condition, measurements can be seen from the screenshot from IKEA website. Instructions can be downloaded from the website, it will be dismantled for collection. I am asking 50 ONO, brand new it costs 399.
Mattress was bought from Argos, I think it was 80 new. Slight mark at the top from a spilled drink.
Any questions please ask.
